Methodology Taxonomy

Got any others to add to revision 1? How about variations on the hated “WATERFALL!” class? Where should the sprawling RUP go? What about “Scrum-but“? Does “kanban” fit into this taxonomy, or is it simply a practice to be integrated within a methodology? What about “Lean“?

Funny, I was wondering the same thing a few weeks ago… Is Semi-Agile Iterative? Then RUP would go under that. You could add V Model under Waterfall. How about a Post Agile classification, then Kanban could go under that?
